[6x + 9] + [4x - 4] = [combine like terms]
6x + 4x + 9 - 4 =
10x + 5
cos 0° = 1
Two vectors are orthogonal[perpendicular] if their dot product = 0
I'm assuming that "O" is the point (0, 0, 0).....if so, we have
< -4, 1, 5 > (dot) < 5, -4, 4 > = -20 - 4 + 20 = -4 .....so......these vectors are not orthogonal
[5 miles / 1 hr] x [5280ft / 1 mile] x [1 hr / 60 min ] = 440 ft/min
Steven must have earned p + 22
So together they earned
p + (p + 22) =
$(2p + 22)
5 + (5/5) + (5/5) =
5 + 1 + 1
5 + 2 =
7
y=3x+5xz factor out an x
y = x(3 + 5z) divide both sides by (3 + 5z)
y / (3 + 5z) = x
The ratio of pi2 to what ????
8C + 25 = 97 where C is the weight of each chair ....subtrct 25 from both sides
8C = 72 divide both sides by 8
C = 9 [lbs] = weight of each chair
4*(27 * 5) = 20 * 27 = 540
